Harvard Psychologist On Teaching Math.

As teachers, many of us are looking around for the best way to teach mathematics.  One person, Jon R Star, a distinguished psychologist at Harvard University,  has spent years researching this topic with professors from Vanderbilt university.  Over time, he has determined better ways to teach math.  We shall look at what he has to say.

It is well known in the field of psychology that the actual process of learning requires people to reach into their brains to find a certain piece of knowledge, pull it out, think about it, and them putting it back into the brain.  This process is referred to as elaborative coding.  The more a person does this process, the more they will have learned, remembered, and understood.  

In math, he stated that it is important to make sense of the material being taught.  Learning is more than just listening to what the teacher says.  Instead, he emphasizes how important it is for students to develop conceptual knowing in mathematics, so it is important for teachers to present the information in a way that students make sense rather than memorizing or internalizing the material.

In fact, Jon recommends that teachers compare two ways of solving a problem by writing each process side by side and then lead a discussion designed to help students understand the difference between the two methods.  It is the discussion because the teacher has asked students why a strategy works and students must dig into their heads to share what they understand.  In addition, listening to other student's reasoning helps reinforce the process of learning since they have to think about it.

It is thought that when students learn multiple ways to solve problems, it deepens their understanding of content. In addition to providing a wonderful benefit to learning, it helps students see math differently.  Instead of seeing math as needing to memorize methods with one method to solve each problem, they are shown that each problem may have multiple ways to solve.

Furthermore, this type of instruction can make class more interesting.  It simply is best to show students the compare and contrast of two methods  but it involves a lot of thinking for both the teacher and student.  There is a concern that both teachers and students might experience information overload or that the teacher might want to take it further by comparing three or four different methods. 

Although many curriculums already show the various methods for solving problems, they don't often focus on the comparing and contrasting step.  In addition, this strategy often requires teachers spend time preparing the visuals so they can teach but it does help students learn more.  Let me know what you think, I'd love to hear.  Have a great day.

How Much Fruit Can Be Removed Before The Display Falls Down!

 

It's a standard scene in the movies.  There is a chase seen in the store where someone touches a piece of fruit, or a kid grabs something and the whole pile falls off and rolls all over the floor.  This scene lead to a person wondering how much fruit can be removed from the display before the whole thing comes tumbling down.

You might wonder why anyone would want to know the answer to this question but apparently the answer to this question is extremely important since it uses the same dynamics that cause avalanches and landslides.

Unfortunately, it is too difficult to figure out how much dirt or snow can be removed before it call comes crashing down as an avalanche or a landslide but the fruit actually offers the opportunity to see how removing objects results in movement.  This study explored the physics of tumbling produce which is the same action that causes avalanches.Since  most fruits are about the same size and shape and end up spread out in a nonrandom, crystal like form.  This makes it easier to look at the impact of removing one item at a time from the overall structure. 

 So the researchers created a computer program that modeled a different number of spheres stacked in a variety of angles. Then they removed spheres one at a time to determine at which angle the display would fall instantly,  not at all, or somewhere in-between. They took it one step further to determine how many objects had to be removed to make the display collapse if it didn't fall on its own.

Furthermore, they concluded the steeper the angle of the display, the fewer the objects removed before it starts falling and the gentler the angle, the more objects one has to remove.  If the slope is gentle enough, the display won't collapse.  They concluded that one could remove about 10 percent of the fruit in the display before it collapses. So if you have 300 fruit stacked in the display and 29 people grab a piece, it will fall when the 30th person takes one.  

Researchers are hoping to take this a bit further by exploring how many objects can be removed when the objects are of different sizes and are randomly arranged. This is more  involved with avalanches and landslides and the results could provide additional knowledge and open up additional avenues of investigation.  Let me know what you think, I'd love to hear.

Why A Pie Chart Is Not The Best Way To Show Data

 

When it is time to teach ways to represent data visually, pie chart is one of the ways taught.  It is one that seems quite popular. Pie charts have long been a staple in visualizing data due to their simplicity and familiarity. However, while they may seem like an appealing choice for displaying information, there are significant drawbacks to their use in accurately conveying data insights. In the realm of data visualization, experts often advise against the frequent use of pie charts due to several inherent limitations that can hinder effective communication of information.

Pie charts are best suited for displaying data with few categories. As the number of categories increases, interpreting a pie chart becomes more challenging. Comparing slice sizes or angles becomes increasingly difficult, especially when the differences between sections are subtle. Human perception struggles to accurately judge the size of pie chart slices, particularly when the slices are close in size. Differences in angles or area can be misleading, leading to misinterpretation of the proportions they represent.

Unlike other types of graphs such as bar charts, pie charts don't readily display precise numerical values. Extracting specific data points or comparing exact quantities within a pie chart requires additional effort, often necessitating supplementary information or labels. For data comparison, side-by-side bar graphs or stacked bar charts tend to be more effective than pie charts. These alternative visuals allow for easier comparison between different categories, making trends and patterns more apparent.

Clutter and confusion can arise when dealing with too many categories in a pie chart. Additionally, labeling smaller slices or categories can overcrowd the chart, reducing its clarity and making it visually unappealing.While pie charts have their limitations, there are instances where they might be appropriate. For example displaying a simple composition of parts to a whole where the differences between categories are distinct and easily discernible. Or presenting data where only a few categories are involved and emphasizing the proportion of each segment is crucial.

Bar charts are ideal for comparing different categories or showing changes over time while stacked bar charts are helpful in illustrating parts of a whole while retaining ease of comparison. Line charts are suitable for displaying trends or changes in data over time and scatter plots are most effective in showcasing relationships between variables.

Pie charts, while popular, come with inherent drawbacks that can impede accurate data interpretation. Their limitations in displaying precise values, comparing data, and handling numerous categories make them less effective in many scenarios. In the realm of data visualization, considering alternative chart types better suited to the specific data at hand is crucial for clear communication and accurate representation. 

By utilizing charts that offer clearer comparisons, better precision, and easier comprehension, one can ensure that data is presented in a more informative and accessible manner, aiding in better decision-making and understanding of complex information. Therefore, while pie charts have their niche uses, their frequent use should be approached cautiously, considering the nature of the data being presented and the desired clarity of communication.

Reading The Math Textbook

Most students I teach have never learned to read a math textbook. I've had to take time to teach them how to read one. It is important for students to know how to find information in a math textbook. Unfortunately, math textbooks are enough different that students need to learn new ways. No matter what, understanding how to effectively read a math textbook is an invaluable skill.

Reading a math textbook requires a different approach compared to reading other subjects. Here are some essential strategies to help you make the most of reading your textbook. First, Begin by skimming through the chapter or section headings, subheadings, and summaries. This gives you an overview of the material you'll be covering.

Next, read actively, not passively. While reading, engage actively with the material. Take notes, underline key concepts, and write down questions or areas you find challenging. Try to paraphrase ideas in your own words to ensure comprehension. Don't forget to take time to work through examples. Math textbooks often include examples to illustrate concepts. Work through these examples step by step, following the author's approach. Pause after each step to ensure you understand the reasoning behind it. Read the explanations of each step as you work through it.

In addition, solve problems as you go through the text. The heart of mathematics lies in problem-solving. Attempt practice problems as you progress through the text. Start with easier exercises and gradually move to more complex ones. Most textbooks are set up with either practice problems with the examples, or in the practice section at the end of the lesson. So work the example and then try similar problems.

If you encounter difficulties or find the explanations unclear, don't hesitate to seek supplementary resources. Online tutorials, videos, or seeking help from teachers, tutors, or fellow students can provide alternative explanations. Youtube has tons of videos on most every mathematical topic. Remember to periodically review what you've learned. Reflect on how the concepts fit together and how they relate to other areas of mathematics or real-world applications.

Reading a math textbook can present certain challenges. Reading a math textbook is more than just deciphering symbols and equations; it's about building a strong foundation of mathematical understanding. By actively engaging with the material, and persistently working through problems, students will enhance their mathematical skills and they will develop more confidence when they do math.
